The invention discloses an anti-scratch TPO automotive interior skin and a preparation method thereof, and relates to the technical field of automotive interiors. The scratch-resistant TPO automotive trim skin comprises a coating, a TPO layer and a PPF foaming layer from top to bottom, the TPO layer is prepared from the following raw materials in parts by mass: 50 parts of thermoplastic polyolefin, 15 to 20 parts of reactive thermoplastic polyolefin, 10 to 20 parts of linear low-density polyethylene, 15 to 25 parts of reinforced polypropylene and 5.6 to 17.5 parts of auxiliaries; the shore hardness of the thermoplastic polyolefin is 83 to 90 A; and the density of the PPF foaming layer is 40-50 kg/m < 3 >. According to the scratch-resistant TPO automobile interior skin disclosed by the invention, the hardness of the TPO automobile interior skin can be effectively improved, so that the scratch resistance of the TPO automobile interior skin is improved, and the problem that the existing TPO automobile interior skin is low in scratch resistance, so that wrinkles are easy to appear is solved.

    本发明公开了一种抗刮TPO汽车内饰表皮及其制备方法,涉及汽车内饰技术领域。本发明抗刮TPO汽车内饰表皮,包括自上到下的涂层、TPO层和PPF发泡层;按质量份数,TPO层的原料包括热塑性聚烯烃50份、反应型热塑性聚烯烃15~20份、线性低密度聚乙烯10~20份、增强聚丙烯15~25份和助剂5.6~17.5份;热塑性聚烯烃的邵氏硬度为83~90A;PPF发泡层的密度为40~50kg/m3。本发明的抗刮TPO汽车内饰表皮,能有效提高TPO汽车内饰表皮的硬度,从而提高TPO汽车内饰表皮的抗刮蹭性能,解决了现有TPO汽车内饰表皮由于抗刮蹭性能较低,导致容易出现皱痕等不良缺陷问题。
